freebsd stable - Feb 2007 - parallel port printer: interrupt storm & system slowdown with 6.2-release

Hi all,

I am having big trouble getting my parallel port printer to work on  
6.2-release. I am getting lots of those famous "stray irq7" messages.
I
already knew that from my 5.4 installation which I previously had on the  
same hardware, so I tried so set the parallel port mode with lptcontrol  
(lptcontrol -d did the trick under 5.4). Tried all the modes, but no  
difference! Using the printer even slows down my whole system to an  
unusuable state. Any ideas what the difference to 5.4 is or what I could  
do?

Regards,
Jost Menke

Put the parallel port in polling mode with 'lptcontrol -p'. Or by
putting 'hint.ppc.0.flags="0x28"' in /boot/device.hints, and
reboot.
